Abstract

Postpartum depression (PPD) is associated with abnormalities in resting-state functional connectivity (RSFC) but the underlying neurochemistry is unclear. We hypothesized that peripartum GABAergic neuroactive steroids (NAS) are related to cortical GABA concentrations and RSFC in PPD as compared to healthy comparison women (HCW). To test this, we measured RSFC with fMRI and GABA+/Creatine (Cr) concentrations with proton magnetic resonance spectroscopy (1 H MRS) in the pregenual anterior cingulate (pgACC) and occipital cortices (OCC) and quantified peripartum plasma NAS. We examined between-group differences in RSFC and the relationship between cortical GABA+/Cr concentrations with RSFC. We investigated the relationship between NAS, RSFC and cortical GABA+/Cr concentrations. Within the default mode network (DMN) an area of the dorsomedial prefrontal cortex (DMPFC) had greater connectivity with the rest of the DMN in PPD (peak voxel: MNI coordinates (2, 58, 32), p = 0.002) and was correlated to depression scores (peak HAM-D17 voxel: MNI coordinates (0, 60, 34), p = 0.008). pgACC GABA+/Cr correlated positively with DMPFC RSFC in a region spanning the right anterior/posterior insula and right temporal pole (r = +0.661, p = 0.000). OCC GABA+/Cr correlated positively with regions spanning both amygdalae (right amygdala: r = +0.522, p = 0.000; left amygdala: r = +0.651, p = 0.000) as well as superior parietal areas. Plasma allopregnanolone was higher in PPD (p = 0.03) and positively correlated with intra DMPFC connectivity (r = +0.548, p = 0.000) but not GABA+/Cr. These results provide initial evidence that PPD is associated with altered DMN connectivity; cortical GABA+/Cr concentrations are associated with postpartum RSFC and allopregnanolone is associated with postpartum intra-DMPFC connectivity.

  • In brain regions associated with emotion and self-perception, neural network connectivity supported by GABAergic signaling is positively correlated with plasma allopregnanolone concentrations in individuals with postpartum depression versus healthy postpartum female individuals.

    “In brain regions associated with emotion and self-perception, neural network connectivity, supported by GABAergic signaling, is positively correlated with plasma allopregnanolone concentrations in individuals with PPD vs healthy postpartum female individuals.33”

    From Effect of Zuranolone vs Placebo in Postpartum Depression (2021) · cites this paper as [33]

    The Demographic and clinical data section (p. 7) reports a positive correlation between postpartum allopregnanolone and intra-DMPFC connectivity in the PPD group, but not in healthy comparison women. The Discussion (p. 8) describes a GABA-mediated contribution as possible, not established; it also reports no correlation between allopregnanolone and measured cortical GABA concentrations. Thus the correlation is supported, but the asserted GABAergic mechanism is overstated. (LLM, conf=0.86)

  • Cortical GABAergic disinhibition in depressive disorders co-occurs with increases in glutamatergic gene expression in the default mode network (DMN).

    “Specifically, cortical GABAergic disinhibition in depressive disorders co-occurs with increases in glutamatergic gene expression in the DMN [24,26,27,28,29,30,31,32].”
  • In women with TRD/treatment-resistant postpartum depression, depressive severity is linked to GABA concentrations in the DMN.

    “In women with TRD/treatment-resistant postpartum depression, depressive severity is linked to GABA concentrations in the DMN [26,27].”

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
